/dev/disk/by-label/elements:
The superblock could not be read or does not describe a correct ext2 filesystem.

fsck died with exit status 8.

A maintenance shell will now be started. CONTROL-D will terminate this shell and
resume system boot.

The thing is that if I type Ctrl-d or enter the maintenance shell the disk is correctly mounted and calls to e2fsck /dev/disk/by-label/elements report no errors.

This is very annoying since I need to type ctrl-d every time the server is rebooted and I would rather not have a keyboard attached to the server at all.
